Abdomen more or less bicoloured, the first sezment pale, the succeeding ones

darkened ; hypopygium brownish yellow, 
Holotype, ¢, Torricelli Mountains, altitude 200-1,000 feet, January, 1939 
(Cheesman ). 
Among the deseribed regional species, the present fly agrees most nearly with 
Elephantomyia (Elephantamyodes) tayloriana Alexander, of New Britain, 
despite the blaek hody coloration and distinetive wing pattern of the latter. The 
hyaline droplet before the arculus is noteworthy.
